VPR221SZ (Z-Foil)

Vishay Foil Resistors

Ultra High Precision Z-Foil Surface Mount Power Resistor

in TO-220 Configuration with TCR of ± 0.05 ppm/°C,

PCR of 4 ppm/W and Load Life Stability of ± 0.005 % (50 ppm)

FEATURES

•

Temperature Coefficient of Resistance (TCR):

•

Any value at any tolerance available within resistance range

INTRODUCTION

The Z-Foil Technology provides a significant reduction of the

resistive component’s sensitivity to ambient temperature

variations (TCR) and applied power changes (PCR).

Model VPR221SZ is a 4 lead kelvin connected surface

mount device which provides high rated power, excellent

load life stability, low Temperature Coefficient (TCR) and low

Power Coefficient (PCR) - all in one resistor. ± 0.05 ppm/°C

Absolute TCR removes error due to temperature gradients.

By taking advantage of the overall stability and reliability of

Vishay Bulk Metal

Z-Foil resistors, designers can

significantly reduce circuit errors and greatly improve overall

circuit performances.

Our Application Engineering Department is available to

advise and make recommendations. For non-standard

technical requirements and special applications, please
